Guides
Picking colors from scratch is the part of a design that stalls everyone. This tool hands the blank page to a language model: describe a theme or mood, choose a style, and get back a palette of named, ready-to-use hex colors.
It works for a moodboard ("sunset over the ocean"), a UI theme ("retro 80s arcade"), or a brand ("minimalist Scandinavian furniture"). If you already have an image to pull colors from instead, use Color Palette Extractor.
How to use it
- Describe a theme or mood — the more specific, the better the result. "Autumn forest at dusk" works much better than "autumn".
- Pick a style: Balanced mixes hues and tones freely, Vibrant leans bold and saturated, Pastel stays soft and airy, Monochrome sticks to tints/shades of one hue, and Earthy stays muted and natural.
- Drag the slider to choose how many colors you want, then press Generate.
- Each swatch comes with a hex code and a short evocative name. Click a swatch to copy its hex code, or download the whole palette as CSV.
What it costs
Priced per color — the Generate button shows the exact credit cost live as you move the slider, so you always know the price before you run it. Only the colors you actually receive are billed. Credits reset daily, and a run that fails costs nothing at all.
Does it generate the same palette for everyone?
No. The model runs with high randomness, so two people asking for "sunset over the ocean" get two different palettes, and so do you if you press Generate twice. Pressing Generate again steers the model away from the colors already on screen, so a second run gives you a genuinely fresh set rather than near-duplicates.
Why did I get fewer colors than I asked for?
Language models occasionally repeat a color when asked for many variations on one theme. Duplicates are removed before the results reach you, so a request for ten colors can return nine. Only the colors you actually receive count against your credits.
Is my theme sent anywhere?
Yes — the text you type is sent to the AI provider that generates the palette, because it's part of the prompt. Don't paste anything confidential into it. Everything else about the tool (your settings, the results) stays between your browser and this site.
Which AI model is behind it?
Whichever one is serving the site at the time. The tool is provider-agnostic and fails over between backends, so a model outage doesn't take the generator down with it.
